Medical device for delivering patches

Abstract

The present invention relates to a medical device and method for treating the body tissue of a patient. The present invention is also directed to a method of making the medical device and a method of using the medical device. More particularly, the invention relates to a medical device which is inserted into the body for delivery of therapeutic patches to the surface of a body lumen, organ or cavity. Specifically, the medical device has an umbrella-like or a basket-like expandable assembly; and a therapeutic patch. The expandable assembly is capable of changing from a retracted position to an expanded position. The expandable assembly can be self-expanding or non-self-expanding. In one embodiment, the medical device comprises an elongated member; an umbrella-like expandable assembly which has a plurality of wire elements; and a therapeutic patch. The therapeutic patch comprises a sheet having two opposing surfaces wherein one of the surface comprises an adhesive material and at least one biologically active material.

Description

1. FIELD OF THE INVENTION[0001]The present invention generally relates to a medical device which is inserted or implanted into the body for delivery of a patch to the surface of a body lumen or an internal body cavity or organ. More particularly, the invention is directed to a medical device that comprises an expandable assembly and a therapeutic patch attached thereon. The medical device enables the administration of a biologically active material on a solid support to the surface of a body lumen or internal body cavity or organ.2. BACKGROUND OF THE INVENTION[0002]Heart failure affects approximately three million Americans, and new cases of heart failure number about 400,000 each year. Congestive heart failure (CHF) is particularly insidious, affecting at least two million Americans, and is a syndrome characterized by left ventricular dysfunction, reduced exercise tolerance, impaired quality of life, and markedly shortened life expectancy. In patients suffering from CHF, decreased ...

AI Technical Summary

Benefits of technology

The present invention is a medical device that delivers a therapeutic patch to the body's lumen or internal organs through a catheter-based patch deployment-delivery system. The invention addresses the limitations of current therapies by allowing for minimally invasive surgery, reducing systemic leakage, and promoting tissue regeneration. The invention provides an expandable patch delivery system that can be non-self-expanding or self-expanding, and a patch with biologically active material and adhesive material. The invention also addresses the issue of thrombogenicity and inflammation associated with current therapies. Overall, the invention provides a safer, more effective, and minimally invasive method for delivering therapeutic patches to the body.

Problems solved by technology

The prior art method of delivering therapeutics using needle injection is problematic because such treatment is too localized.

Also there are problems associated with patch delivery whereby a biologically active material is incorporated into a patch.

Currently, affixing such delivery vehicles to the myocardium is only achieved with maximally invasive surgical techniques (i.e. open-heart surgery).
